Question

20.00 g of aluminum (al) reacts with 78.78 grams of molecular chlorine (cl2) all of each reactant is completely consumed and a single product what is the mass in gram of the product

Answer 1

The mass of the product is 98.78 g.

The word equation is

aluminum + chlorine → product

20.00 g + 98.78 g → x g

If each reactant is completely consumed, the Law of conservation of Mass tells us the mass of the product must be 98.78 g.
